VIBRA-TIN G MACHINE FOR MASSAGING PURPOSES.

Specification of Letters Patent.

Patented Oct. 15, 1907.

Application filed March 14:, 1904. Serial No. 198,065.

To all whom it 1n ay concern:

13e it known that I, JAY VAN TUvL DANIELs, a citizen of the UnitedStates, and residing at London, England, have invented cei'tain new anduseful Improvements in Vibrating Machines for Massaging Purposes, ofwhich A the following is a speci ication.

The invention relates to that class of massaging machines capable ofbeing driven by any mechanical means in which an unbalanced wheel isrotated at high speed to produce the vibrations.

The invention consists of the features and of the cornbination andarrangements of parts hereinafter described and particularly pointed outin the claims.

The invention is illustrated in the accompanying drawings in which:

Figure 'l is a side view of the device. Figs. 2 and 3 are face andcentral sectional views oi the double fly wheel, Fig. 3 being taken online Z-Z of Fig. 2.

In these drawings l is a casing having a handle 2. In the casing l areassembled the operative parts of the device which comprises the gearwheels or pinions 3, 4, 5 and (i, the shaft 7, the bevel pinion 8 ofwhich gears with the pinion 3 and the double fly wheel 9 on the end ofthe shaft 7. l0 is a crank connected with the axle of the pinion G forrotating the train o gears.

'As shown the double fly wheel 9 consists oi two disks All and l2 havingholes 13 and 14 respectively. These disks are mounted upon the shaft 7and are held in place By slackening this nut the disks can be turned ormoved upon each other, and the relative positions of the holes 13 and 14can be altered and thus the balance or center of gravity of the wheelchanged and the intensity of thek vibrations or taps thus be graduatedat will.

In operation any suitable part of the casing l may be rested or pressed.upon the part of the body to be massaged. The operator holds the devicein one hand by means of the handle 2 and with the other hand he turnsthe crank l0, which by means ofthe train of gears rotates the shaft 7and the fly Wheel 9 which being of greater weight on one side than uponthe other imparts vibrations to the casing which are transmitted to thebody of the patient. Ii desired a Contact plate may be connected to thecasing and this plate instead oi the casing itself is placed on the partof the body. As this contact plate is Well known and forms no part of myinvention I have not illustrated it.

W hat I claim and desire to secure by Letters Patent is z* l. ln amachine of the class described, a disk mounted upon a revoluble shaftthe center of gravity of which is non-incident to the axis of the shaft,a second disk monnted upon the same shaft of like character, means forvarying the positions of the center of gravity of the two disks relativeto one another and for rigidly securing the two disks to the shaft inany desired position, substantially asshown and described.

In a machine of the class described, a frame, a revoluble shaft mountedin the frame, a disk of solid metal having a large hole on one sidebetween the axis and the periphery to alter the center of gravitythereof, a like disk mounted upon the shaft with the iat face thereofabutting against the face of the tirst disk, and means for securing' thetwo disks rigidly together and to the shaft in any desired position soas to vary the position of the two holes thereof, substantially as shownand described.

In witness whereof I have hereunto set my hand in presence of twowitnesses.
